2-Ethyl-5-methoxy-N,N-dimethyltryptamine (EMDT), also known as 2-ethyl-5-MeO-DMT, is a tryptamine derivative which is used in scientific research. It acts as a selective 5-HT6 receptor agonist, with a Ki of 16 nM, and was one of the first selective agonists developed for this receptor.[1][2] Its affinities for many other targets have also been reported.[2] EMDT inhibits both short- and long-term memory formation in animal studies, and this effect can be reversed by the selective 5-HT6 antagonist SB-399,885.[3] Additionally, it is active in the tail suspension test, suggesting that it could be an effective antidepressant.[4]
